QULTIVATOR.

Application f led March 24, 1920. Serial No. 368,477

To all whom it may concern:

Be it known that I, DOUGLAS G. ScLAN- DEBS, a subject of Great Britain, residing at tain new and useful Improvements in Girl-- tivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will. enable others skilled in the art to which it .appertains to. make and use thesame. v I

This invention relates to improvements in cultivators and more particularly to those of the straddle-row type,one object of the invention-being to so construct such a cultivator that it may be readily guided by the operator by reason-of its pivotal connection with a wheeled draft frame or truck, and to so connect the cultivator frame with the latter that it may be adjustable vertically and so that the cultivator may be inverted and caused to be supported on runners which may travel over the, ground when it is desired to transport the cultivator from place to place, as from one field to another or over a roadway.

A further object is'to so construct a cultivator that certain of the shovels shall operate effectually to throw the soil toward the plants and cover weeds which may be adj a-.

cent to the latter and so that certainother shovels shall throw the soil in a direction to fill the furrows made by the first-mentioned shovels.

A further object is to so construct a straddle-row cultivator that it shall be strong and substantial and capable of successfully withstanding all strains to which it may besubjected. v I

With these and other objects inview, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings; Figure 1 is a plan view of a cultivator embodying my improvements; Figure 2 is a side elevation; Figure 3 is an edge view of the arch 7 Figure 4 is a similar view of the arch 8; Figure 5 is a side view of one of the shovels and its supporting standard, and Figure 6 is a rear view of a shovel and standard.

1, 1 represent longitudinal frame beams 'made approximately in the form of inverted ing in horizontal arms 4:, and rearwardly inclined members 5 terminating in approximatelyhorizontal arms forming handles 6.

Theframe beams 1, .1 are suitably spaced apart and disposed at an acute anglerelatively to each other, and their forward portions are connected bytwo transverse arches 7 and 8 approximately equal in height to the depth of the frame beams. The forward arch 7 is provided at its lower end with lateral arms 9 which are secured to the base portions 2 of the frame beams 1 by means of bolts 10. The rear arch is provided at its lower end with lateral-arms 11 secured to the base portions 2 of the frame beams by bolts 12 and said arms 11 project laterally beyond the frame beams for a purpose hereinafter explained.

The frame beams and arches are connected by diagonal braces 13,-each of which is connected at-its forward end with one of the frame beams and at its rear end with the other frame beann the intermediateportions of said braces being secured to the tops of the arches 7 and 8. I v Curved shovel standards 14 are secured to the frame beams at the juncture'of the rear arch 8 therewith and provided at their lower ends with foot portions 15 Which receive shovels 16 and to which said shovels are securely bolted. Lateral beams 17 are bolted to the frame beams at. the juncture of the front arch 7 therewith and, extending later- V allyand rearwardly therefrom, are bolted to theouterend portions ofthe arms 11 of the rear arch The lateral-beams extend rearwardly from their connection with-the arms 11 and have, secured thereto, the upper ends of shovel standards 14*, the latter having seats 15 to which rear shovels 16 are secured. The shovels 16 are so disposed that they will operate to throw the soil toward the plants and cover any weeds which may be growing near the latter and the shovels 16 are so set that they will throw the soil in a direction to fill the furrows made by the shovels 16.

A wheeled draft frame 18 is provided for and constitutes, in effect, a part of the cultivator structure,-'said wheeled frame being constructed for attachment of draft animals or other draft means. A. draft link or bar 19 is pivotally connected by a vertical bolt 20 with a its scope and henceldo? t-wis'h-to by the runners and afj'ts yfp igy coupling 22 is pivotally connected by means of a horizontal bolt 23, the"pivo talconnec whereby] the connection Fbfthefid avv bars =1. be easilyguidedfbvthefiperato I f the ivotal fonnection a. 2 h efcon ne ing saldbeam frame Wheeled frame;'and-"'t;l1e cultivator "'may :be forward shov l-1 standards se r .,,l W, V" V r i 1A., raised and'lowered by reason of the"p1votal bea n frarnes sand reargarch secured to said standards connection "of the cliaii bar's 25 vifith coupling 22 at 26.
